PRUNING IMPLEMENT.

SPECIFICATION forming part of Letters Patent No. 774,039, dated November1, 1904.

Application filed February 20, 1904. Serial NO- 194540- (No model.)

To to whom it may concern.-

Be it known that 1, JAMES B. CARPENTER, a citizen of the United States,residing at Plantsville, in the county of Morgan and State of Ohio, haveinvented certain new and useful Improvements in Pruning Implements, ofwhich the following is a specification.

This invention relates to new and novel improvements in that class ofdevices commonly called pruning implements.

The invention particularly aims to provide an implement of this classcombining in a single article means for engaging limbs preparatory toclipping or cutting them, cutting devices, and sawing devices.

For a full description of the invention and the merits thereof and alsoto acquire a knowledge of the details of construction of the means foreffecting the result reference is to be had to the following descriptionand accompanying drawings.

\Yhile the essential and characteristic features of the invention aresusceptible of modification, still the preferred embodiment of theinvention is illustrated in the accompanying drawings, in which Figure lis a perspective view showing an implement constructed in accordancewith my invention. Fig. 2 is a sectional view through the shank of theimplement, parts broken away to show more clearly the means foradjusting the movable saw-arm. Fig. 3 is another sectional view similarto Fig. 2, taken on a line about at right angle to that upon which Fig.2 is taken. Fig. l is a detail view, parts broken away, embodying themodification. Fig. 5 is a detail perspective view of the fulcrumed blockused in connection with the structure shown in Fig. 4.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

The invention comprises a shank 1, adapted to be attached at its lowerend to a handle 2, the upper end of the shank being extended andprovided with a knife-head 3. The shank is secured to the handle 2 bymeans of suitable detachable fastenings, such as 4, which admits of useof different sized handles to support the shank 1 under certainconditions of service. It will be obvious that in certain "instances itis desirable to use a very long handle in pruning the uppermost limbs ofthe tree, whereas in other instances a short handle only is necessaryfor convenient manipulation of the implement. Adjacent the end of theshank which carries the knife-head 3 is disposed a transverse cross-bar5,.which extends laterally from opposite sides of the shank, as will bereadily seen. The cross-bar 5 has attached to the end portions thereofthe upper ends of the saws 6, the lower ends of the said saws beingadjustably secured to the ends of. a pivoted cross-bar 7, carried by thelower end portion of the shank 1. The saws 6 are attached to the pivotedcross-bar 7 by means of adjustable set-screws 8, preferably, the upperends being pivotally secured to the rigid cross-bar .5, as shown at 9.The setscrews 8 admit of a certain amount of adjustment of the saws 6 intightening and loosening same; but in order to secure a maximumadjustment of the saws the pivoted cross-bar 7 is adapted for a slidablemovement relative to the shank 1. In order to admit of the slidablemovement of the cross-bar 7, as be- .fore mentioned, the shank l isprovided with angularly disposed elongated openings 10. The cross-bar 7extends through one of the elongated openings 10 of the shank, saidcrossbar being provided with a pivot-pin 11, disposed laterally thereonand extended through the other of the angularly-disposed elongatedopenings 10. A wedge 12 is preferably used to cooperate with the pivotedcross-bar 7 to actuate the said bar in its slidable movement, said wedgebeing received by one of the openings 10 and bearing against thecross-bar 7 adjacent the pivot-pin 11 thereof. From the foregoing itwill be noted that the saws 6 are adapted for a preliminary adjustmentby means of the setscrews 8, and that further and simultaneousadjustment may be had when necessary through actuation of the wedge 12and slidable movement of the cross-bar 7.

An engaging hook 13, having a knife-edge, is projected laterally fromthe knife-head 3, and this hook is adapted to engage limbs or the likepreparatory to cutting same, as the case may be. The hook 13 is veryconveniently located relative to the knife-head 3 and may be used to cutsmall branches and twigs.

In Fig. 4 is a somewhat modified construction of means for effecting theslidable movement of the cross-bar 7, as shown. In this form of theinvention the shank l is threaded adjacent the openings 10 therein, andan adjustable collar 14 is mounted upon the threaded portion thereof.The collar 14 bears against a fulcrumed block 15, against which thecrossbar 7 obtains a pivotal hearing. The crossbar 7 is provided with arecess 16, which receives the fulcrumed extension 17 of the block 15.cross-bar l7 and effects simultaneous adjustment of the saw 6.

It will be noted that the saw 6 may be readily detached when broken andothers substituted therefor, and that these saws are adapt ed forasimultaneous or independent adjustment, as may be found most desirable.

Having thus described the invention, what is claimed as new is 1. In apruningimplement, the combination i with a shank provided at its upperend with a cuttinghead, spaced cross-bars disposed upon the shank, sawshaving corresponding ends secured to the cross-bars aforesaid, and meansfor effecting independent or simultaneous adjustment of said saws.

2. In a pruning implement, the combination with a shank provided at itsupper end with a cutting-head, a rigid cross-bar carried by Adjustmentof the collar 14 actuates the the shank, a second cross-bar also carriedby the shank and slidable With reference to the rigid cross-bar, sawsconnected at corresponding ends with the rigid and slidable crossbars,and means for effecting slidable movement of the slidable cross-bar.

3. Inapruningimplement, the combination with a shank having its upperend provided with a cutting-head, a rigid cross-bar carried by the shankadjacent the cutting-head aforesaid, a cross-bar disposed at the lowerportion of the shank and slidable with reference to the rigid cross-bar,saws pivotally secured at corresponding ends to the rigid cross-bar andadjustably secured at their opposite ends to the movable cross-bars, andengaging means cooperating with the movable cross-bar to effect slidableadjustment thereof.

4. In a pruning implement, the combination with a shank provided at itsupper end with a cutting-head, ahook projected laterally from thecutting-head, an upper rigid cross-bar, the shank being provided with anelongated open ingadjacent its lower portion, a movable crossbarpivotally and slidably supported in said opening, and saws connected atcorresponding ends with the rigid and movable cross-bars.

In testimony whereof I affix my signature in presence of two witnesses.
